Oh, I should have added that my resolution is 1680x1050 with no intention on upgrading my monitor.
I should revise my initial statement: I would *like* to overhaul my system next year, but if there is something I can do in the present that might eke out another year of performance, that would be even better, since an overhaul would be quite costly (almost new everything given my system at the moment).
If my CPU is bottlenecking it as much as it will, do you guys think I should pick up maybe an AMD X4 955 processor for about $110? It's a bandaid solution, but if that means I won't HAVE to upgrade next year, then that would be great.
